</dd></dl>

<p>Normally, you would use the <tt class="xref py py-func docutils literal"><span class="pre">os.path.is*()</span></tt> functions for testing the type
of a file; the functions here are useful when you are doing multiple tests of
the same file and wish to avoid the overhead of the <tt class="xref c c-func docutils literal"><span class="pre">stat()</span></tt> system call
for each test.  These are also useful when checking for information about a file
that isn&#8217;t handled by <a class="reference internal" href="os.path.html#module-os.path" title="os.path: Operations on pathnames."><tt class="xref py py-mod docutils literal"><span class="pre">os.path</span></tt></a>, like the tests for block and character
devices.</p>

</dd></dl>

<p>The interpretation of &#8220;file size&#8221; changes according to the file type.  For plain
files this is the size of the file in bytes.  For FIFOs and sockets under most
flavors of Unix (including Linux in particular), the &#8220;size&#8221; is the number of
bytes waiting to be read at the time of the call to <a class="reference internal" href="os.html#os.stat" title="os.stat"><tt class="xref py py-func docutils literal"><span class="pre">os.stat()</span></tt></a>,
<a class="reference internal" href="os.html#os.fstat" title="os.fstat"><tt class="xref py py-func docutils literal"><span class="pre">os.fstat()</span></tt></a>, or <a class="reference internal" href="os.html#os.lstat" title="os.lstat"><tt class="xref py py-func docutils literal"><span class="pre">os.lstat()</span></tt></a>; this can sometimes be useful, especially
for polling one of these special files after a non-blocking open.  The meaning
of the size field for other character and block devices varies more, depending
on the implementation of the underlying system call.</p>
<p>The variables below define the flags used in the <a class="reference internal" href="#stat.ST_MODE" title="stat.ST_MODE"><tt class="xref py py-data docutils literal"><span class="pre">ST_MODE</span></tt></a> field.</p>
